The euro has recently come under attack—not from hedge funds or speculators and not in the same panic that gripped the markets following the debt crisis in peripheral European countries such as Greece, Italy and Spain.

This time the attack is coming from two of the foremost central bankers of Europe. Moreover, the attack is against the continued rise of the euro against the U.S. dollar, which the European Central Bank (ECB) believes is leading to deflationary trends.

At the latest International Monetary Fund meeting in Washington, Mario Draghi, president of the ECB, told journalists that the euro’s strength was one of the main factors leading to disinflationary trends. Draghi believes the euro’s strength knocked off between 0.40 and 0.50 percentage points of inflation over the past 18 months.1

“The strengthening of the exchange rate requires further monetary stimulus,” Draghi said. “That is an important dimension for us.”

But Draghi isn’t the only leader of a European central bank concerned with the strength of the euro. The head of the Swiss Central Bank, Thomas Jordan, tied his fate to the euro following the financial crisis, when money flowed to Switzerland, causing the Swiss franc to show incredible strength as a safe-haven currency but leading to deflationary pressure and putting recessionary pressure on Switzerland. The Swiss National Bank (SNB) took a bold step of capping the Swiss franc at 1.20 per euro in September 2011. Now Jordan thinks the euro is overvalued, again putting pressure on Switzerland’s economy.

Jordan said, “The Swiss franc remains highly valued, and in order to maintain adequate monetary conditions in Switzerland so that we can maintain price stability, and in order to not fall back into negative inflation, we have to maintain the minimum exchange rate. … We have a strong euro against the dollar, and we have an even stronger Swiss franc against the dollar, so what we need is probably both a weakening of the Swiss franc and a weakening of the euro against the dollar.”2

The question is, What will the ECB do, besides talk tough about the euro causing deflationary trends? The ECB’s balance sheet has been shrinking—more a sign of financial tightening conditions than monetary easing—as banks repay their long-term refinancing operations (LTRO) programs that were enacted during the crisis period.

The ECB has shown reluctance to engage in further quantitative easing (QE) programs or expand its balance sheets by buying assets such as government bonds. The political situation in Europe is complicated, in that, achieving a consensus among central bank governors spread across Europe is very challenging.

Recent supportive comments from Bundesbank head Jens Weidmann mark a “radical softening” of the German Central Bank’s stance with respect to QE.3 Austria’s Central Bank head, Ewald Nowotny, has also suggested that QE should not be off the table.4 But the European Union (EU) framework itself imparts additional questions in regard to sovereign debt purchases. One economist has suggested the ECB buy U.S. treasuries with additional QE, as there would be no favoritism being shown in what countries’ bonds were selected and no fears about monetizing government deficits, and it would have the effect of directly countering fears of an overvalued euro. Yet this is not the route the ECB is leaning toward.

Going to a Negative Deposit Rate

Rather, the talk is twofold. The ECB seems to prefer targeting purchases of asset-backed securities and possibly looking to implement a negative deposit rate. Supporting securitized loans while also placing a tax on deposits at the ECB would potentially create incentives for banks to expand their lending programs and refuel expansionist policies.
